A significant fraction of the labor force consists of employed workers who are part-time unemployed (underemployed) in the sense that they are unable to work as much as they prefer. This paper develops a search and matching model to study the design of optimal unemployment insurance in an...

In this paper we study the effects on the survival rate in employment of a scheme that facilitates gradual retirement through working time reductions. We use information on the entire labour market career and other observables to control for selection and take dynamic treatment assignment into...

In this paper we investigate the recent fall in unemployment, and the rise in part-time work and labour market participation amongst prime-aged Germans. We show that unemployment fell because the Hartz reforms induced a large fraction of the long-term unemployed to deregister as jobseekers....

We conducted an experiment in which we hired workers under different types of contracts to evaluate how flexible working time affects on-the-job productivity in a routine job. Our approach breaks down the global impact on productivity into sorting and behavioral effects. We find that all forms...

The official U.S. unemployment rate is an inadequate measure of actual labor market conditions. This poses a major challenge for researchers and confuses both the public and policy makers. A new definition of unemployment is proposed. It considers those part-time workers who would like to work...

The gender pay gap and the gender gap in employment remains persistent in Europe despite the basic assertion of gender equality under EU law. We assess the factors that influence the gender pay gap and gender employment gap across European countries. Therefore, we use an unbalanced panel of 31...

Empirical tests of the theories on the relationship between political competition and economic performance generate a puzzle: data tend to support the theory at the lower levels of government, but not in panels of countries. We argue that the larger set of policy instruments reduces the tax...

In this paper we discuss the global negotiations now underway and aimed at achieving new climate change mitigation and other arrangements after 2012 (the end of the Kyoto commitment period). These were initiated in Bali in December 2007 and are scheduled to conclude by the end of 2009 in...
